[[Image:Detectors summary 3.png|thumb|right|250px|This tree diagram shows the relationship between types and classification of most common particle detectors. Credit: [[commons:User:Wdcf|Wdcf]].]]
'''Radiation detectors''' provide a signal that is converted to an electric current. The device is designed so that the current provided is proportional to the characteristics of the incident radiation.

Some materials can operate at room temperature. For high performance gamma- and x-ray detectors high atomic number, large bandgap and high electron mobility (e.g., ~1100 cm<sup>2</sup>/V·s) result in high intrinsic µτ (mobility-lifetime) product and high degree of charge collection and excellent spectral resolution.
